Bound the memory used when parsing uploaded packages, so instances with low memory limits survive non-standard packages. 1. Metadata files are read through a size-limited reader, archives themselves stay unbounded so large payloads keep working 2. zstd decoding caps the window at 128 MiB, the zstd CLI default 3. RPM headers go through a first-party reader with rpmlib's size and array count limits that allocates only what the upload contains, until https://github.com/sassoftware/go-rpmutils/pull/44 is released. Signing still verifies the payload digest, and its signature header matches rpmsign's byte for byte 4. Swift and NuGet read the zip entry they size-checked, a duplicate name could stand in for it before 5. Terraform states check `LIMIT_SIZE_TERRAFORM_STATE` before parsing, NuGet symbol PDBs share a 256 MiB budget 6. Oversized container configs are rejected instead of stored without metadata, invalid Vagrant boxes answer 400 instead of 500 Signed-off-by: techknowlogick <git@tklk.dev> Co-authored-by: techknowlogick <git@tklk.dev> Co-authored-by: silverwind <me@silverwind.io> Co-authored-by: techknowlogick <techknowlogick@gitea.com>
